Thanks for all the input guys. I guess I'm searching for a 4.3 r&p.

Bringing this back from the dead :
I currently have a 4.1 Torsen in my 95 ITA Miata , running a Stahl header that makes good HP up top , but gives up some TQ down low ... We're adding a MSPNP and Louie R is tuning this week help that.
My primary tracks are TWS 2.9 CCW , MSRH CW , MSRH CW
The 4.1 is terrible @ MSRH CW
The 4.1 is less terrible @ MSRH CCW
The 4.1 is less than perfect @ TWS 2.9 CCW
I've heard many conflicting opinions about which gear , but we all agree the 4.1 is less than optimal
Any other thoughts ?
I bought my 1.6 with a 4.10 and hated it! I was always above or below my power band in the corners and I ALWAYS got my butt kicked on the start. I switched to a 4.77 (Kia Sportage R&P), Megasquirt, and upgraded the header. It completely transformed the car!
Granted, it's a 1.6 and the MiDiv tracks I race are shorter and more technical. I shift a lot more but I've learned to adjust. My times have really improved and I'm getting podium finishes.
Don't forget there's a 4.44 R&P out there to.

Have I read everything correctly... if I have a 1.6 and want to change from the 4.3 to a 4.44, I can find a R&P from a 1st gen Rx7? I usually find myself at VIR or CMS, I think the 4.44 should help keep the rpms up in the slow corners.
Thanks in advance!

The 1.6 diff is a smaller ring gear diameter- you'll need to use the 1.8 housing. At that point, lots of stuff will just bolt right in.

But would that be IT legal?

Nope, Not IT compliant. In IT the 1.6 car is stuck with its stock diff housing, in SM the 1.6 is allowed to upgrade to the 94-97 later 1.8 housing which uses first gen RX7 gears. The same gears are used in the RX8, the Honda S2000 and the Kia Sportage as well.
All posts are made by a fat old guy with a crappy old car that isnt supported by a factory anymore and therefore should not be taken seriously, EVER
